3MZ1410A磨床砂轮修整器倒抬油缸行程开关的动作如图1所示。撞块2压轴3前移,来顶微动开关6,实现油缸行程。倒抬油缸每班换向达500次以上,轴3将套4内孔磨成很扁的椭圆形,使轴3常被卡住不能前移。而一旦发生前移,微动开关就可能被撬坏。从而造成每两个月内就需更换轴3及套4,约每星期更换一次微动开关。这样,既费力、费时又费财。我们经过仔细分析,主要是套4磨损。造 3MZ1410A grinding wheel dresser lift cylinder stroke switch action shown in Figure 1. Collision block 2 finale 3 forward, to the top micro-switch 6, to achieve cylinder stroke. Lift the cylinder commutation of more than 500 times per shift, the shaft 3 will be 4 sets of holes grind into a very flat oval, the shaft 3 is often stuck can not move forward. In the event of a forward move, the microswitch may be pry bad. Resulting in every two months on the need to replace the shaft 3 and sleeve 4, about a micro switch every week. In this way, laborious, time-consuming and expensive. After careful analysis, we mainly set 4 wear. Made
